Miley Cyrus has vowed to never return to acting, insisting she wants to do music "for the rest of her life". The former Hannah Montana star admits she thought she wanted to work more in Hollywood when her Disney show ended in 2011, but after filming 2012 movie So Undercover on the back of LOL and episodes of sitcom Two and a Half Men, she decided it wasn't the right path for her. During an extended version of MTV documentary Miley: The Movement, which aired in America on Sunday (06Oct13), she said, "I thought after my show I was gonna act. "I did one movie and I came back and said, 'I'm never doing that again. I'm going to do music for the rest of my life'." Cyrus has not appeared on the big screen since 2012.
